Shadowing is an informal way for someone to learn what it is like to perform a particular job at a workplace.
An individual follows around, or shadows, the worker already in that role.
A shadow, or a wick, is a line found on a candle in a candlestick chart that is used to indicate the price of a stock has fluctuated relative to the opening and closing prices.
Essentially, these shadows illustrate the highest and lowest prices at which a security has traded over a specific time. The candlestick also has a wide part, which is called the "real body."
Candlesticks are used across various measures, such as time and ticks, and various frames such as one minute, two minutes, 1,000 ticks, or 2,000 ticks. No matter what the measure or frame, the formation, and rules work the same.
